The New Cambridge Shakespeare For this updated critical edition of King Lear, Professor Halio has added a new introductory section on recent stage, film, and critical interpretations of the play. He gives a comprehensive account of Shakespeare"s sources and the literary, political and folkloric influences at work in the play; a detailed reading of the action; and a substantial stage history of major productions. Professor Halio chooses the Folio as the text for this edition. He explains the differences between the quarto and Folio versions and alerts the reader to the rival claims of the quarto by means of a sampling of parallel passages in the Introduction and by an appendix which contains annotated passages unique to the quarto. An updated reading list completes the edition.
